Automatic Shut-Off Valves

Automatic Shut-Off Valve ASOV-14CW is a replacement part for a standard residential Reverse Osmosis (RO) System. The ASOV (Auto Shut Off Valve) is a key component that is used in standard Reverse Osmosis (RO) based Point-Of-Use (POU) drinking water treatment systems. The device saves as much as 15,000 Gallons of water per year by shutting off the water once your tank is full. It has been tested and certified by NSF International under NSF/ANSI Standard 58.

Automatic Shut-Off Valve ASOV-14CW is manufactured with NSF listed materials. It uses a diaphragm between the feed water and treated water to control the flow of feed water into the treatment system. The product is designed to shut off at 65% of supply line pressure. This means that the ASO Valve will shut off production, when the tank pressure reaches around 65% of the incoming line pressure.

Automatic Shut-Off Valve ASV-ERP-JG 90% for Permeate Pumps is designed to shut off at 90% of supply line pressure. This means that the valve automatically shuts off production when the tank pressure reaches approximately 90% of the incoming line pressure to indicate the tank is full. The ASO valve is ideal for saving thousands of gallons of water.

You can use this Auto Shut Off Valve with residential Reverse Osmosis Systems with a permeate pump. The Standard Reverse Osmosis systems auto shut-off valves cut the water supply when tank pressure is at 65% of feed water pressure. To maximize the Permeate Pump efficiency, it is recommended that you should replace the existing shut-off valve with this 90% valve which will allow the tank to pressurize to 90% of feed water pressure. This ASOV is highly recommended in low water pressure applications.

In this device, all tube connections are 1/4" quick connect with "in" and "out" labeled on the top. The Auto Shut Off Valve comes with four 1/4" quick connect fittings. Easily insert 1/4" tubing directly into the ASO Valve. Reverse Osmosis Systems without an Automatic Shut-Off valve continually send rinse water to the drain even when the tank is full. Learn More

Clip for Automatic Shut Off Valve CLP-ASVW is a single clip for mounting automatic shut-off valves. It can be used with the ASOV-14CW, ASOV-14BW, ASOV-14QW, ASOV-14QB shut off valves. The CLP-ASVW clips on to the automatic shut-off valve (ASOV) for mounting to the reverse osmosis system or other flat surface. The screw is not included with the automatic shut off valve clip.
